Installation went wrong

[Dakhaas]

Hi,

after installing and having run the installation previously , I somehow wrecked it, adnd did it again, and again unistalled because somehow I mixed up manual and express installations. Do you still understand? Me neither.

Thing is… I have Domoticz also running on the same Rpi, and it may not be harmed as it is keeping up with my energy meter and usage,
So starting over with a fresh Raspbian (jessie, full) is out of the question. For the same reason I can not use Domoticz for home automation. (or you may have a solution for Domoticz to not flood the MTT server with energy data when turning on MQTT).

So: something is seriously wrong with the openHab installation. But I want it back because it recognized the Orvibo smart plugs.
Please help.

anything useful in /var/log/openhab2/openhab.log ?

did you try to clear the cache?

what is your java -version ?

[Dakhaas]

/var/log/openhab2/ only has an empty readme.txt.
fine, clear cache… how? (reboot twice)
java helper library 1.8.3 dfs 1
java helper for web 3.1.1-2
javascript common 11
etc. there are a lot of java packages and versions, specify pls.

[Dim (Angelos)]

what is the output of the command in the Linux shell ? (java -version)

clear cache… how?

Clear the Cache

Often when one encounters a problem with OH, particularly after an update, OH will refuse to run or certain parts of OH stop working. Some reported errors include: 500 or 404 errors when accessing the UIs lots of exceptions from Jetty or other core components in openhab.log OH refuses to start at all The first step in debugging the problem is to clear the tmp and cache. Installed OH If you are running an installed OH (openHABian, installed using apt or yum): openhab-cli stop openhab-cl…

This raises a bunch of alarms.

If you cannot afford a little down time on the Domoticz then nothing else should be installed in this RPi. And your primary focus right now should be to make it so you have a good backup and restore plan for Domoticz because it will fail at some point.

Then look to install OH on some other machine or install it on the same machine knowing you can quickly restore Domoticz if the bed arises.

It is frankly not worth your time to try and fight OH on this same machine at this point. If keeping Domoticz running is this critical then you need to focus on making it rock solid with backup and restore that takes next to no time. And then nothing else should run on this machine.

Nothing that is so critical that you can’t afford a few hours of down time should run on the same machine as other stuff. The risk of down time is too high.

[Dakhaas]

a few hours downtime is not critical, it’s just that I do not want to do the calculations. The energy meter itself is standalone and transmits to the company anyway. In fact I just installed monit because Domoticz has been down for 2 days
I realise that tinkering with the Rpi and home automation will disrupt some running services. But it should be able to run them all without much trouble. I do not want to give up my other Rpi just to be safe with this one.
Then to be even more safe, I should set it up in a different building to get the maximum out of the redundancy. Even then … with only 1 energy meter sensor, it would be better even to have the data in the cloud somewhere. That should be a priority project.
However I want to have fun in the mean time and have my smart devices taken care of too. OpenHab should be able to handle that.
And that gets me back to this issue.

[rlkoshak (Rich Koshak)]

Well, here is the problem. When OH runs into problems like this, the most efficient use of your time and the time of the users on this forum will be to do a fresh install.

There is not enough information provided for us to really help. And even if there were, we are not physically present in front of this device and we can’t root around to try to figure out what the problem is. You didn’t even tell us how you installed OH.

You can look through the syslogs or use (journalctl)[https://www.linode.com/docs/quick-answers/linux/how-to-use-journalctl/] to see if there is something more useful logged to the syslog that tells you what might be wrong. What ever it is, it is going to be something fundamental like it can’t find java or it doesn’t have permission to read or write to something critical.

[Dakhaas]

I did use a fresh install , like on the Package Repository Installation page, then uninstall after the crash, then again fresh.again uninstall and again install. Somehow the uninstall did not completely work, I think.

java version “1.8.0_65”

that’s very old for OH2. The recommended is >161

can you upgrade your JVM using either Zulu or Oracle?

[Dakhaas]

that’s very old for OH2.

the whole raspbian is from september. I imagine they use up to date parts…

[rlkoshak (Rich Koshak)]

the whole raspbian is from september. I imagine they use up to date parts…

They do not.The default versions in the default repos are always behind, sometimes embarrassingly so.

Java 1.8.0_65 will not work.

As documented in the Prerequisites section of the installation documentation, the latest 32-bit Zulu version of Java 1.8 is the recommended Java to run OH on a RPi.

Installation Overview

[Dakhaas]

ok. no openhab for me then, all java installs refuse to work.

openjdk completes with failures, oracle I hate (from earlier days)

[rlkoshak (Rich Koshak)]

If you are on an RPi, why even fight this battle?

Look at https://www.openhab.org/docs/installation/openhabian.html which will give you a preconfigured OS with all the prerequisites already installed and configured.

If you don’t want to start from scratch, you can start with a stock raspbian and follow the manual instructions.

[Dakhaas]

because I do not want a preconfigured openhab os. Openhab is not the primary program it should run. It has to run the energy meter and Domoticz, everything else is secundary. I could probably run it on one of the windows pc’s available, but they tend to use about 5 times as much power. (very little for a pc huh) and I want to stop running them 24/7 just because the power gets too expensive here.
So the Rpi should run 24/7 and also manage the iot I am building.
Openhab had the option to become the package to go for, but when it depends on some shit like java which even oracle dumped already, it seems openhab is not for me.

[rlkoshak (Rich Koshak)]

openHABian is just a script or a series of scripts. If you follow the manual steps you can install and configure as much or as little as you want. There is nothing that prevents you from running other programs with openHABian. It just automates all of this installation and configuration stuff.

But if you don’t want to accept the help from all the work people have done to make this easier for you then perhaps openHAB isn’t for you. We like to offer help here.

Oracle may have dumped it but plenty of others have picked it up and continue to use it. And for the record, we do NOT recommend Oracle’s Java to run openHAB. OpenJDK has known problems on RPis that make it unsuitable. We recommend Zulu. I don’t speak your language so I can’t begin to tell you why importing the gpg key failed.

If you are worried about openHAB interfering with your other services, you can run it in a Docker container. Then you don’t have to install anything but Docker and openHAB will be isolated from the other programs you want to run.

[Dakhaas]

I appreciate your help. Even if my reasoniing may indicate otherwise.
Docker looks like something between vmware and sandbox. On a rpi that goes too deep for me. I could just run linux on a vmware image if I wanted to go that way,
By the way… I keep images of the Rpi sd-card on the pc. Did restore from september, reinstalled monit and now java. might do a new image before trying openhab install again, So I have a relatively clean system to work with.

[rlkoshak (Rich Koshak)]

If you do start from scratch, I’d start with either openHABian or install a manual instead of openHABian on a stock raspbian minimal.

Like I said, there is nothing special about openHABian. Is just a bunch of scripts that installs OH and optionally other services like Mosquitto, InfluxDB, Amanda and such. But it’s just a bunch of scripts. Once it’s run all you end up with is regular old Raspbian, it off you prefer Ubuntu with some software installed and configured. You can then install and configure any other software you want to run on it too.

But the key is the openHABian scripts are known to work. You should not have to face problems like these and using openHABian doesn’t prevent you from installing anything else you want to.
